Cement-based ultrahigh-performance artificial stone slab and production and mounting method thereof

Abstract

The invention discloses a cement-based ultrahigh-performance artificial stone slab and a production and mounting method thereof. The cement-based ultrahigh-performance artificial stone slab comprisesan ultrahigh-performance concrete slab body embedded with a stainless steel mesh piece; the stainless steel mesh piece is provided with nuts, ends of the nuts are flush with the back of the slab body,and the slab body is manufactured by means of strong vibration, high compression and vacuum pumping. Based on the basic requirements of basic material and formula process necessary for the ultrahigh-performance concrete, the stainless steel mesh piece capable of improving breaking strength is added, and the slab is manufactured by means of strong vibration, high compression and vacuum pumping. With the advantage of screwing between nuts and screws, the slab can be connected with metal connectors in any shapes, dry hanging with wet combining and drying hanging with or without keels can be achieved, the optionally cut slabs can be combined and connected by the metal connector strips to form line shapes, the slabs can be clamped with thermal-insulating boards made of any materials to form athermal-insulating integrated board through nuts and metal strips by long screws, and further, quick and safe mounting of the slab can be achieved.

Description

technical field [0001] The invention relates to the field of architectural decoration, in particular to a cement-based ultra-high-performance artificial stone plate and a production and installation method. Background technique [0002] Existing building walls are decorated with stone-effect plates, which mainly include natural stone plates and ceramic imitation stone plates. Natural stone plates are decorative plates made of naturally formed stone through cutting, grinding, sandblasting, etc. The ceramic imitation stone board is a board with natural stone effect by firing clay at high temperature. There are two main installation methods: wet paste and dry hang. 1. Wet paste: Wet paste is to use sticky mortar to paste the board on the wall to be decorated. It is a rigid connection. Due to the thermal expansion and contraction caused by outdoor wind pressure, rain, and temperature difference, the viscosity of the mortar will be accelerated. In addition, due to the high weigh...

Problems solved by technology

1. Wet paste: Wet paste is to use sticky mortar to paste the board on the wall to be decorated. It is a rigid connection. Due to the thermal expansion and contraction caused by outdoor wind pressure, rain, and temperature difference, the viscosity of the mortar will be accelerated. In addition, the weight of the board is relatively large, so it is easy to cause the board to fall off, and the rigid connection is extremely poor in shock resistance. The current wet paste method is only used for decoration at the low-rise of the building, and the use of high-rise buildings is basically prohibited.

2. Dry hanging: The dry hanging of the board first needs to be installed on the wall to be decorated, and the metal dragon skeleton used to carry the board is installed. Since the naturally formed stone itself is in a solid state, the embedded parts for the external connection cannot be placed inside. Ceramics are also unable to place embedded parts because of high-temperature firing. When installing the two types of plates, only grooves or holes can be made on the side of the plates or holes can be drilled on the back of the plates, so that metal connectors can be used to connect and install the load-bearing frame. Stone and ceramics are relatively brittle. The connectors stuck in the side grooves or holes during installation need to bear the weight of the board. If the board is thin, the thin wall is easy to cause chipping and falling off; the back is punched, and the thinner board Punching holes are easy to break, and shallow holes are low in strength and poor in safety. Therefore, the thickness of dry-hanging stones is now stipulated to be no less than 25mm, and the time for ceramics to be dry-hanged is relatively short. To ensure its safety, the weight of the dry-hanging stone per square meter exceeds 65 kilograms, so that the dragon frame used to carry the plate also needs to maintain a certain strength to carry its weight, so the production and installation of the metal dragon frame is costly and heavy The cost of panel installation is also very high, and due to the heavy weight of the panel, the structure of the house needs to be enlarged to carry it, which also increases the cost of housing construction, stone mining damages the environment, and high-temperature firing of ceramics wastes energy and easily causes pollution

[0003] After searching, it was found that in order to solve the above problems, in the patent (CN2014100884568) a kind of artificial slab stone production and its installation method, and in the patent (CN201410694568X) the cement-based artificial slab stone installation method combined with dry hanging and wet paste, although to a certain extent The above problems are solved, but the board has disadvantages such as low strength, low density, poor weather resistance, high water absorption, and poor freeze-thaw resistance. The pre-embedded nuts are placed independently, and the hanging strength is low; the pre-embedded hooks are in the The back of the board is protruding, which can easily affect the assembly line processing of the board, and the protruding hook is not easy to stack, and it is easy to cause the board to break
